NHTSA Complaint #11362560 — 2016 MERCEDES-BENZ S550

I WOKE UP ONE MORNING AND WAS ASTOUNDED TO FIND A LONG DIAGONAL CRACK ACROSS THE PANORAMIC SUNROOF OF MY 2016 MERCEDES-BENZ S550. I CONTACTED MERCEDES AND WAS TOLD TO BRING THE CAR TO A DEALERSHIP FOR EVALUATION TO DETERMINE WHETHER THIS WAS DUE TO OUTSIDE INFLUENCE OR A MANUFACTURER'S DEFECT. THEY DETERMINED THAT IT WAS A "STRESS CRACK" AND STUCK ME WITH A BILL FOR $13,000. THIS IS A 2016 MODEL CAR WITH 50K MILES ON IT WITH A SUNROOF THAT SPONTANEOUSLY CRACKED. WHAT IF MY WIFE AND YOUNG CHILDREN WERE IN THE CAR WHEN IT STARTED TO CRACK? THE RESPONSE FROM MERCEDES IS UNACCEPTABLE. THIS IS A VERY DANGEROUS MANUFACTURER'S DEFECT WHICH MUST BE ADDRESSED BEFORE SOMEONE GETS SERIOUSLY HURT.
